TÓM TẮT
The Bipolar plate plays an essential role in a proton exchange membrane fuel cell(PEMFC), it performs many important functions such as contributing reactants through gasdiffusion layers to the MEA, current collection, providing structural support to the MEA,water management & thermal management and so on. Therefore, the bipolar plate designentails the design of the flow fields on both surfaces of the plate with optimum designparameters to assume responsibility for the stability and high performance of fuel cell. Inthis paper, a numerical analysis-based design of bipolar plate is investigated to enhance theperformance of PEM fuel cell through a comparative evaluation of the fuel cellperformance when flexibility using the serpentine flow-field and the serpentine flow fieldwith sub-channels design for anode and cathode bipolar plate. The results show that usingthe serpentine flow-field with design as the bipolar plates appropriately has manyadvantages in preventing from the cathode flooding and anode drying; as the result,improving fuel cell performance.
